I accidentally added the compliance test hacks only to intel_dp_hotplug() which doesn't even get used on any DDI platform. Put the same crap into intel_ddi_hotplug(). Cc: Imre Deak <imre.deak@intel.com> Fixes: 193af12c ("drm/i915: Shove the PHY test into the hotplug work") Signed-off-by:

Currently we claim to use TPS7 when using TPS4. That is just confusing, so let's fix the debug print. And while we're touching this let's add the customary encoder id/name as well. v2: Add MISSING_CASE() (Manasi) Reviewed-by:

This pulls a large chunk of the pll calculation code out of intel_display.c to a new file. One function makes sense to be an inline, otherwise this is pretty much a straight copy cover. Also all the remaining hooks for g45 and older end up the same now. Signed-off-by:

Let's not enable the 4:4:4->4:2:0 conversion bit in the DFP unless we're actually outputting YCbCr 4:4:4. It would appear some protocol converters blindy consult this bit even when the source is outputting RGB, resulting in a visual mess.

In the next commit where we split PWM related backlight functions from higher-level backlight functions, we'll want to be able to retrieve the backlight level for the current display panel from the intel_panel_bl_funcs->setup() function using pwm_funcs->get(). Since intel_panel_bl_funcs->setup() is called before we've fully read in the current hardware state into our atomic state, we can't grab atomic modesetting locks safely anyway in intel_panel_bl_funcs->setup(), and some PWM backlight functions (vlv_get_backlight() in particular) require knowing the currently used pipe we need to be able to discern the current display pipe through other means. Luckily, we're already passing the current display pipe to intel_panel_bl_funcs->setup() so all we have to do in order to achieve this is pass down that parameter to intel_panel_bl_funcs->get(). So, fix this by accepting an additional pipe parameter in intel_panel_bl_funcs->get(), and leave figuring out the current display pipe up to the caller. Signed-off-by:

There are a number of functions that "init" pps in various ways. Try to find some more consistency in the naming. Rename: - intel_dp_init_panel_power_sequencer -> pps_init_delays - intel_dp_init_panel_power_sequencer_registers -> pps_init_registers - intel_dp_init_panel_power_timestamps -> pps_init_timestamps as this is what the functions do. Skip the intel_ prefix here to emphasize these are static and not exported. No functional changes. Reviewed-by:

The DP PHY vswing/pre-emphasis level programming the driver does is related to the DPTX -> first LTTPR link segment only. Accordingly it should be only programmed when link training the first LTTPR and kept as-is when training subsequent LTTPRs and the DPRX. For these latter PHYs the vs/pe levels will be set in response to writing the DP_TRAINING_LANEx_SET_PHY_REPEATERy DPCD registers (by an upstream LTTPR TX PHY snooping this write access of its downstream LTTPR/DPRX RX PHY). The above is also described in DP Standard v2.0 under 3.6.6.1. While at it simplify and add the LTTPR that is link trained to the debug message in intel_dp_set_signal_levels().
